(d) Write the equation that links current, potential difference, and resistance. The potential difference across a piece of wire is 2.1V The current in the wire is 0.30 A Calculate the resistance of the wire. Write any equation that you use. __ Resistance=

Answer 1

2.1 / 0.30 = 7 Ohms

Answer 2

This question covers the concept of "Ohm's Law," a fundamental principal in physics related to electricity. The law states that the current running through the conductor between two points is directly proportional to the voltage across two points, and it is usually illustrated as V=IR where V represents potential difference (voltage), I represents current and R - resistance. From the provided details the Question we have V=2.1 volts and I= 0.30 ampere. The question asks us to find the value of R (resistance), which can be found using the rearranged format of Ohm's Law: R=V/I
