Calculate the energy transferred by a 12 V hairdryer, running on a current of 0.50 A, that is left on for 8.0 minutes. List all the information in symbol form and change into appropriate and consistent SI units if required. E =? Use the correct formula. Calculate the answer by putting the numbers into the formula.

The most important Energy Transferred Equation is E = Pt (Power × Time), which can be used in Electrical Problems and Mechanics. Other Energy Transferred Equations are E = QV (Charge × Voltage), and E = IVt (Current × Voltage × Time).

E = IVt. We can calculate the energy transferred in a circuit by using the formula energy = current x voltage x time.

Power is a measure of how quickly energy is transferred. The unit of power is the watt, W. The more energy that is transferred in a certain time, the greater the power of the appliance. It is calculated using the formula: where P=power, I=current and V=voltage/p.d.

Potential difference (p.d. in volts, V) is the energy transferred per unit charge as electric charge moves from one point to another in an electric circuit. It is measured with a voltmeter, which is always wired in parallel across a circuit component. Just think of all the electrical appliances you use - all need supplying with energy to work!

Thermal capacity is the amount of energy required to raise the temperature of a substance by 1K or 1 o C. Note that a change in temperature of 1 o C is equal to a change of 1K because their graduations are equal.
