Q. 6 C

# The three r

Given

Battery = 12V

Resistance (parallel) = 5 Ω, 10 Ω and 30 Ω

Formula used

Parallel Resistance formula

Ohm’s Law

V = IR

V = voltage

I = current

R = resistance

Calculation

To solve part (a) we first have to solve part (b)

(b) Equivalent resistance

Hence, R = 3 Ω

(a) Total current

I = 4 A
