7 hours ago Ques. Calculate the potential difference of a 10-ohm resistance cable when a current of 20mA is sent through it. (3 marks) Ans. First, use the formula to compute the potential difference, where R = 10 and I = 20mA. As R x I = V. So, V = 10 x 20 x 10-3 A = 0.2 volts. Hence potential difference V will be 0.2 volts. Ques.

What Is the Formula for Calculating Potential Difference?
Preview
1 hours ago The formula for measuring potential difference is V=W/Q and this formula is known as Ohm's law. In this equation, V is equal to the potential difference, W is the energy transferred or work done and Q is the amount of the charge. Potential difference can also be measured using the formula V=IR, where I is the current charge and R is the resistance.
