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.
Current: Current is basically the rate of the flow of electric charge generally through a medium, i.e. current i = dq/dt.Where 'q' represents charge and 't' represents time. In D.C. circuits if a suitable medium is present, voltage difference causes the flow of charge i.e current.
