An experiment to determine factors of resistance in wires

B Current is directly proportional to the voltage. A fourfold increase in the voltage would cause a fourfold increase in the current. A circuit is wired with a power supply, a resistor and an ammeter for measuring current. The ammeter reads a current of 24 mA milliAmps.

Determine the new current if the voltage of the power supply was See Answer A circuit is wired with a power supply, a resistor and an ammeter for measuring current. But current is also inversely proportional to the resistance; a doubling of the resistance will halve the current.

These two factors offset each other and there is no overall change in the current. But current is also inversely proportional to the resistance; a halving of the resistance will double the current. So the new current can be found by tripling and then doubling the old current of 24 mA.

So the new current can be found by halving and then halving again the old current of 24 mA. Use the Ohm's law equation to provide numerical answers to the following questions: An electrical device with a resistance of 3.

Gather, record and process data. Several expressions link the factors together. Resistance measured in ohms (Ω) is found by Ohm’s law, R=V/I. V represents voltage, a measure of electrical so that the resistance of the wires of the probes and alligator connections could be.
