An illustration from Easy electrical experiments and how to make them;, 1918, leaf 38
if the resistance be veryhigh, the current may be very small even though the *E. M. F.be large. So we see that a circuit with a high E. M.

The number of volts in a circuit gives us… … ***=■ Circuit of Water.in volts, divided by the resistance in ohms. This is a very im-portant law and every student of electricity should become famil-iar with it. Thus, suppose that we know the resistance of anincandescent lamp to be 200 ohms. What current will flowthrough it when it is attached…
