Current voltage and resistance answer key. If the current of a circuit is 9 amps and the resistance is 12 ohms then what is the voltage. What is the potential difference across a hand held fan that has a resistance of 120 ω and a current of 50 ma. This brings us back to georg ohm. What is the resistance in a circuit if a potential difference of 110 v causes a current of 10 a.

Voltage is always measured between two points. Explain if you can the relevance of these facts to electrical safety. A potential difference voltage across an electrical component is needed to make a current flow through it. Current may be measured at a single point at a cross section of a conductive path.

Current voltage and resistance current is the rate of flow of electric charge. Tes global ltd is registered in england company no 02017289 with its registered office at 26 red lion square london wc1r 4hq. Ohm defines the unit of resistance of 1 ohm as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere or 6 241 10 18 electrons.
