Question

If a 10-volt battery is placed across a 2-ohm resistance (R = 20), a current of

Answer 1

Answer: current I = 0.5 A

Explanation:

Given that the

Potential difference V = 10V

Resistance R = 20 ohms

According to ohms law

V = IR

Where

V = potential difference

I = current

R = resistance

Make I the subject of formula

I = V/R

I = 10/20

I = 0.5 Ampere
