What formula is used to calculate current in a circuit?
Current (I) equals voltage (E) divided by resistance (R)
What formula is used to calculate voltage in a circuit?
Voltage (E) equals current (I) multiplied by resistance (R)
What formula is used to calculate resistance in a circuit?
Resistance (R) equals voltage (E) divided by current (I)
