What is the ratio of current to voltage called?
the resistance
The ratio of voltage to current is called the resistance, and if the ratio is constant over a wide range of voltages, the material is said to be an “ohmic” material.

What can you say about the ratio of voltage to current How does it compare with the value of the resistance in the circuit?
This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. But, if we increase the resistance, then the current will decrease.
What is the ratio of voltage across a conductor to the current it carries?
Mainly terms for electricity, but there are a few concept questions as well. There are 77 terms/questions, but only 10 are shown at a time….Electricity Terms and Concepts.
| A | B |
|---|---|
| current | the rate that electric charges move through a conductor |
| resistance | the ratio of the voltage across a conductor to the current it carries |
What is the ratio of voltage and electric current in a closed circuit?
constant
The ratio of voltage and electrical current in a closed circuit Remains constant.
How do you find the resistance ratio?
The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm’s law, I = V/R, can be used to predict the behavior of the material.
What is the resistance equation?
V is the potential difference in volts , V. I is the current in amperes (amps), A. R is the resistance in ohms, Ω The equation can be rearranged to find the resistance: R = V ÷ I Question.
What is the relationship of current voltage and resistance?
The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
