Units

I'm sure you know the SI unit for distance, mass, time, force, energy, power: meter (m), kilogram (kg), second (s), newton (N), joule (J), watt (W). For the derived units, N, J, and W, be sure you know that N is kg m/s², J is N∙m, and W is J/s.

Now the electricity and magnetism units: Charge is in coulombs (C), electric field is N/C = volt/meter, potential or voltage is in volts (V) = J/C, Capacitance is in farads (F) = C/V, current is in amperes (A) = C/s, resistance is in ohms (W ) = V/A, magnetic induction or magnetic field (corresponding to electric field) is in tesla (T) = N/(A∙m), inductance is in henrys (H) = T∙m²/A = V∙s/A=W∙s. A watt is a volt∙amp (W = V∙A).

It is also worth knowing that an ohm farad is a second. So is a henry/ohm. Take a few hundred W F to memorize the above, then go to something more fun (the main page on electricity & magnetism, etc.

Or go to one of the other main physics pages:
