Question

According to Ohm's law, what are the two variables that affect the amount of current in a circuit?

A.Voltage difference and resistance
B.Resistance and electrical pressure
C. Voltage difference and electrical pressure
D.Conductor material and resistance

Answer 1

V =IR
Voltage difference and resistance.

Answer 2

V=IR --> I={V/R}

Answer 3

by definition ohm's law gives the relation between
amount of current in a circuit, I
and Voltage difference, V
resistance, R will be constant
this gives the relation \[I= V \div R \]

thus the answer is [A]
