T4D: Ohms law relationships
T4D01:
What formula is used to calculate current in a circuit?
Current (I) equals voltage (E) divided by resistance (R)
Current (I) equals voltage (E) multiplied by resistance (R)
Current (I) equals voltage (E) added to resistance (R)
Current (I) equals voltage (E) minus resistance (R)
T4D02:
What formula is used to calculate voltage in a circuit?
Voltage (E) equals current (I) multiplied by resistance (R)
Voltage (E) equals current (I) divided by resistance (R)
Voltage (E) equals current (I) added to resistance (R)
Voltage (E) equals current (I) minus resistance (R)
T4D03:
What formula is used to calculate resistance in a circuit?
Resistance (R) equals voltage (E) divided by current (I)
Resistance (R) equals voltage (E) multiplied by current (I)
Resistance (R) equals voltage (E) added to current (I)
