A group of cells consisting of four rows connected in parallel, each row containing five cells connected in series. If you know that the electromotive force of each cell is (1.8 V), and its internal resistance is (0.8 0), and the external resistor of the circuit is (17 0), calculate: 1. The electromotive force of the group of cells? 2. Cell group resistance? 3. The current passing through the external resistor?

Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
