The relationship between Voltage, Current and Resistance forms the basis of Ohm’s law. In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down. ... Very nice tutorial, well explained.

To find the amount of current, you can use the triangle above to the formula for current: I = V/R. Now you can calculate the current by using the voltage and the resistance. Just type it into your calculator to get the result: I = 12 V / 600 Ω I = 0.02 A = 20 mA. So the current in the circuit is 20 mA. Example: Choosing a Resistor for an LED

You can calculate the resistance of the wire with the resistance equation. Let's say you have a 120-watt light bulb plugged into a wall socket. The voltage is 120 volts, and a 120-watt bulb has 1 amp flowing through it. You can calculate the resistance of the filament by rearranging the equation: R = V/I. So the resistance is 120 ohms.
Explanation: By dividing the voltage by the resistance, we determine that the current is 3 amperes. Example 2: Calculating Resistance. Problem: A circuit has a 9V source and a current of 0.5A. What is the resistance? R = 9V / 0.5A = 18Ω. Explanation: The resistor must have a resistance of 18 ohms to allow 0.5 amperes of current when 9 volts ...
