Question

1. When a 60V battery is connected across an unknown resistor there is a un
of 5A in the circuit. Find the value of the resistance of the resistor:
a) 1.2 b) 120
C) 120
d) 1200

​

Answer 1

Answer:

We know

V=IR

V=voltage, R=resistance, I=current

So R=V/I

=60/5 ohm

=12 ohm

Answer 2

Answer:

12 ohm

Explanation:

by ohm's law

V=IR

then, R= 60÷5

R=12ohm
