The Simple Circuit

As the resis- tance of the variable resistor is increased the power dissipated in the circuit.

. As the charging carriers pass through them the energy is passed to the electrical components inside a circuit. An electric circuit contains a variable resistor con- nected to a source of constant potential difference. To measure the potential.

In an operating electrical circuit the source of potential difference is called the energy source where current flows from the higher potential to the lower potential. The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. Compared to the total potential drop across circuit A the total potential drop across circuit B is.

24 In an operating electrical circuit the source of potential difference could be A a battery B a voltmeter C an ammeter D a resistor 25 The diagram below represents a 30ohm resistor connected to a 12volt battery.
