A charge of 1.0 coulomb flows for 2 minutes, what is the current?
A current of 100mA is flowing for 10 minutes, what is the charge passedCoulombs
A current of 10mA passes a charge of 100 Coulombs. How long is the
supply switched on for? seconds
Consider this circuit
the resistor network shown, calculate
the total resistance of the combination
the p.d. across each resistor:
4ohm: V, 10 ohm: V,
20 ohm: V
the current through each resistor.
4ohm: A, 10 ohm: A,
20 ohm: A
the circuit shown, a d.c. supply of p.d. V and negligible internal
resistance is connected to 400 W
and 1600 W
resistors arranged in series.
A voltmeter of resistance 2000 W
connected across the 400 W
resistor gives a reading of 8.0 V.
a) the magnitude of the
