What is the value of current in the circuit based on the measured values of voltage and resistance?

I= 

Calculate the power dissipated by a 68 Ω resistor when carrying a current of 150 mA.

P= 

Calculate the power dissipated by a resistor carrying a current of 2A with a measured voltage drop of 12V.

P= 

Power may be defined as:

The terms ‘work’ and ‘energy’ are directly related to:

For a fixed supply voltage, a slight increase in circuit resistance will cause the circuit current to:

For any fixed resistance, an increase in the applied voltage will cause the circuit current to:
