In which circuit the current through Aluminium and nichrome are the same?

In which circuit the current through Aluminium and nichrome are the same?

In series connection, current through the two wires is the same.

What is the relationship between the length of the nichrome wire and resistance?

As the length of wire increases, the resistance increases.

Which has more resistance nichrome or Aluminium?

Nichrome wire has very high resistivity. Resistivities of copper and aluminium are almost same but the resistivity of copper is slightly greater than that of aluminum.

Why does a nichrome wire gets heated in an electric circuit whereas nichrome does?

Why does a nichrome wire get heated in an electric circuit whereas nichrome does? Nichrome due to its high resistivity does not allow the electric energy easily to pass through it. This electrical energy is changed into heat energy. So nichrome wire gets heated in an electric circuit.

Which has higher resistance two wires of the same length and diameter of Aluminium and Nichrome at constant temperature?

Among the two wires having similar length and radius, Nichrome wire gets heated up more as compared wire since resistivity of Nichrome is more than that of Copper.

Which is the wire that heated more when the circuit is switched on?

Nichrome wire gets heated up more. So more the resistance of a wire, more will be heat generated in it. Hence, we can say nichrome wire gets more heated up as compared to the copper wire.

What is the relationship between the length of wire?

The length of a wire when it is longer, causes the resistance to increase, when the wire is shortened the resistance decreases. A larger diameter wire will carry more current than a small diameter will. A longer wire will eventually carry less current, because the resistance increases as the length increases.

What is the relationship between wire length and current?

Does a longer wire increase resistance?

The longer the wire, the more resistance that there will be. There is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse.

How does Nichrome wire heat up?

Nichrome due to its high resistivity does not allow the electric energy easily to pass through it. This electrical energy is changed into heat energy. So nichrome wire gets heated in an electric circuit.

Why is Nichrome wire used in electrical heating appliances?

Note: A nichrome wire is used as a heating element because of its high melting point and high resistivity (low conductivity) also. Having a high melting does not allow the nichrome wire to melt easily when a large amount of heat is produced. Hence, nichrome has high resistivity and low conductivity.

Why is the power loss of nichrome wire greater than copper wire?

Justify your answer. Resistance of nichrome is greater than copper wire of same length and same radius, because the former has greater resistivity. In series, Power loss P= I 2R. Because of higher resistance power loss and heating up of nichrome wire is more than that of copper.

What happens when two wires of the same length are connected together?

So when we connect two wires of the same length together in series, one of nichrome and the other of copoer, the resistance of the nichrome wire will be very high compared to the same length of copper wire. In a series circuit, the same current will pass through the two wires.

Why does nichrome dissipate more heat than copper?

Hence the nichrome is more resistive or less conductive than copper. If there is high resistance connected in series and current flows across it then obivously the voltage across nichrome will be more than the copper given by the equation-. V=IR (ohm’s law) and thus nichrome dissipates more heat than copper.

What is nichnichrome made of?

Nichrome is an alloy of nickel and chromium and sometimes other elements such as iron. A typical blend is 80\% nickel and 20\% chromium.
