A 63 Ω resistor is connected to a 4.7 V battery
a) When the switch is closed, calculate the current I. Answer in units of A.

A 7.4 Ω resistor is connected to a 4.7 V battery When the switch is closed, calculate the current I.

A 69 Ω resistor is connected to a 4.7 V battery When the switch is closed, calculate the current I.

  • Physics - ,

    In each case the current is I = V/R

    V = 4.7 Volts R is the given resistance

    Get to know Ohm's law. Do the numbers.
