Statement: An electrical circuit has three resistors which three resistors with two having dropped 5 V and 12 V. A current of 50 mA is flowing through the circuit. Find the value of input source?

Solution:

1. Using color coding chart, find the value of the resistor, which is 240 ohms in the present case. (Red, Yellow, Brown = 240).

2. Apply Ohm's law to find the voltage across 240 Ω resistor. V = IR = 50 mA * 240 Ω = 12 V.

3. Apply Kirchhoff's Voltage law to find the source voltage:

Source voltage = 5 V + 12 V - 12 V + 3 V = 8 V

So the source is 8 V. You should also know the concept of polarity for solving this problem.

Fascinating information I haven’t been experienced such information in quite a long time.
