What happened next was this: Jahlil phoned his father, Chucky Okafor, who had moved from Oklahoma back to his hometown of Chicago a few years before. Chucky heard it immediately in his sonâs voice, which was somewhere between a cry and a scream. The only words Chucky could make out: âMama.
Current is the rate at which charge is flowing. Resistance is a materialâs tendency to resist the flow of charge (current). So, when we talk about these values, weâre really describing the movement of charge, and thus, the behavior of electrons.
Power is the rate at which energy is added to or removed from a circuit by a battery or a load. Current is the rate at which charge moves past a point on a circuit. And the electric potential difference across the two ends of a circuit is the potential energy difference per charge between those two points.
