How do you calculate the resistance

WebUsing the current formula, find the resistance of the circuit. Solution: To find the resistance (R) of the circuit: Given: V = 20V, I = 5 Amp Using Current formula R = V/I R = 20/5 R = 4Ω Answer: The resistance of the circuit 4Ω. FAQs on Current Formula How Do You Calculate Current Using Current Formula? WebThe formula for resistance is: R = ρL/A Where: R is the resistance of the material (in ohms) ρ is the resistivity of the material (in ohm-metres) L is the length of the material (in metres) A is the cross-sectional area of the material (in square metres)

WebTo calculate internal resistance, we use a potentiometer to first calculate the voltage across the battery, with no current through it. Then we attach a resistor in parallel to the battery and recalculate the voltage across it. Since the current flows, this time the balancing length is smaller. Using the battery equation, we calculate the ... WebOhms Law Calculator Please provide any 2 values and click "Calculate" to get the other values in the ohm's law equations V = I × R and P = V × I.
