A positively charged atom or group of atoms can be called a(n) _____. anion anode cation cathode User: A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes. How much current runs through the vacuum? 900,000 amps 60,000 amps 4.2 amps 0.24 amps
Weegy: A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes . [ How much current runs through the vacuum ? * there is a rule : P(w) = VI Where : P(w) is the electric power ( = 500 watt or 500 J/s ) V is the potential difference ( = 120 volt ) I is the current intensity ( = unknown ) So : 500 = 120 * I I = 500 / 120 I = 4.16 Ampere ( approximately 4.2 Ampere ); Therefore the answer is 4.2 amps. ] User: The electricity that is delivered to our homes from regional generating stations moves over transmission lines that are _____. high voltage and low current high voltage and high current low voltage and high current low voltage and low current User: When you turn on a television, the electrical circuit _____. closes opens does not move User: Which of the following factors influence the electrical resistance of a circuit? conductivity of the materiallength of conducting wiresdiameter of conducting wirestype of battery installed (More)
