The energy transferred to a bulb is 320 J when 64 C of charge passes through it. Calculate the potential difference across the bulb.
V = E / Q. = 320 J / 64 C. = 50 V

A 4.5 V battery is connected to a 1.0 resistor and a 5.0 in series with each other. Calculate the total resistance of the two resistors.
Total resistance = 1.0 + 5.0 = 6.0

A 4.5 V battery is connected to a 1.0 resistor and a 5.0 in series with each other. Calculate the current through the resistors.
Current = battery potential difference / total resistance. = 4.5 V / 6.0 . = 0.75 A
