Current Electricity Part 2

Electrical circuit is shown in the diagram. Now, let's draw the equivalent circuit.Equivalent resistance of the circuit,
Req=‌

50×20

50+20

Req=‌

100

7

Ω
According to voltage division rule,
voltage across the 10Ω resistance of the circuit,
V10Ω=170×(‌

10

10+‌ 100 7

)
V10Ω=70V
The value of the x to the nearest integer is 70 .
