Question

Three resistance 2Ω, 3Ωand 5Ω are connected in series and a p.d of 20V is applied across the terminals of combination. The p.d across 5Ω resistance is

Answer 1

Answer:

10 volts

Explanation:

When connected in series, current is constant throughout the circuit.

Let's calculate current,

Equivalent resistance=10 ohm

V=IR

20=I×10

I=2A

Again applying the formula,

V=IR(to find the p.d across 5 ohm resistor)

V=2×5

V=10V

Hope this helps you

Answer 2

Explanation:

the total resistance is 10 ohms that is 2+3+5=10ohms

So,V=iR

20=i×10

i=2A

So, now V=iR

V=2×5

V=10volts
