Electric-charge units {charge measurement} are one mole of electrons {faraday} (F) or total charge {coulomb, charge} (C) moved one meter by one newton. 1 F equals 96494 C.
Electric charge, in coulombs, divided by time, in seconds is electric current {electric current measurement} in amperes (A). Currents are typically 0.1 A to 5 A. Radio current is 1 A.
Electric energy, in joules, divided by charge, in coulombs, is electric potential {potential measurement} in volts (V). Small-battery voltage is 1.5 V. Car-battery voltage is 12 V. Magnetic field has unit {gauss}.
Electric potential, in volts, divided by current, in amperes, is electrical resistance {resistance measurement} in ohms, which has upper-case omega symbol.
Electric-potential change divided by current change is electric capacitance {capacitance measurement} in farads (F). Capacitors have farad range from 1 F to 500 F.
Electric-current change divided by electric-potential change is electrical inductance {inductance measurement} in henrys.
