Application of Ohm's Law

Author: E.E. Kimberly

Ohm's Law states that the direct current in a circuit is equal to the impressed direct difference of potential divided by the circuit resistance. Thus, by equation (1-2),


Example 3-1. - In Fig. 3-1 let the 230-volt direct-current generator G be connected to the terminals of the resistor R whose resistance is 50 ohms. Find the current.

Solution. - The current is I = V/R = 230/50 = 4.6 amp.
