# Using a current source (4.5 V), a voltmeter, an ammeter, a switch, a rheostat, connecting wires

Using a current source (4.5 V), a voltmeter, an ammeter, a switch, a rheostat, connecting wires, and a resistor marked Y2, assemble an experimental setup to determine the operation of an electric current across a resistor. Using a rheostat, set the current in the circuit to 0.2 A. Determine the work of the electric current in 10 minutes. In the answer form: 1) Draw a diagram of the electrical circuit 2) Write down the formula for calculating the work of the electric current, 3) indicate the results of measuring the voltage at a current of 0.2A; 4) write down the value of the electric current work.

1) schematic
2) A = UIt
3) U = 4.5V
4) A = 4.5 * 0.2 * 600 = 0.9 * 600 = 540 J
