Question

In the circuit given below, five resistances of \(10 \Omega\), \(40 \Omega\), \(20 \Omega\), \(30 \Omega\), and \(60 \Omega\) are connected as shown to a battery of 18 volts.
Potential difference between points A and B

Hint:

Potential difference (\( V \)) is calculated using \( V = IR \), where \( I \) is the current and \( R \) is the resistance between two points.

Answer 1

Voltage across \( R_1 \) (which is equivalent to \( 8 \Omega \)): \[ V_{AB} = I \times R_1 = 1 \times 8 = 8 \, \text{V} \]
