Question

To control current in circuit we used
Resistance Voltage

Answer 1

Answer:

A simple circuit is one in which there is a single voltage source and a single resistance. One statement of Ohm's law gives the relationship between current I, voltage V, and resistance R in a simple circuit to be I=VR I = V R . Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A.\
