A voltmeter with a resistance of 10,000 ohms is connected across a circuit that has a voltage of 50 V. What is the current flowing through the voltmeter?

An 8-pole induction motor, fed from a 50 Hz supply, is running at a speed of 720 rpm. The slip of the motor is:

Calculate the power consumed by an incandescent lamp rated at 250 V when it carries a current of 0.3 A and has a resistance of 600 Ω (using P = I2R or P = V × I with actual working values).
