If a circuit runs with a charge of 50 Coulombs flowing for 10 seconds, calculate the current. Then analyze how the increase of charge to 100 Coulombs affects the current over the same period.
💡 Hint: Think about the basic current calculation.
A device draws power of 120 W from a voltage of 240 V. Calculate the current and also, if a second device which draws double the power is added, what will be the new total current?
💡 Hint: Think about the power formula and then add the currents based on the devices.
