Weblimit the flow of current around a circuit and can prevent damage to components. Resistors used in electrical circuits have a tolerance of how much power they allow into a circuit - the smaller that tolerance is, the less likely the circuit will be overloaded and damaged, but the more expensive the resistor will be. WebThese electrons carry energy from a source around the circuit. There are two equations you need to recall that include electrical charge, Q. Use these equations to answer the following: a) A current of 2 A flows in a circuit that contains a single lamp, calculate the amount of charge that passes through the lamp in 3 s.
