Ohm's law - solved math problems, problem solving and knowledge review. The constant of proportionality is called the resistance of the material and has the units of voltage volts over current amperes, or ohms. In principle, it is relatively simple to measure the resistance of a strand of wire. Connect a battery to a wire of known voltage and then measure the current flowing through the wire.

The 8 volt the circuit flows clockwise the first resistor is a 2 ohm. A circuit is the combination of voltage source and resistors forming a closed loop like the one shown above.

In some cases ohm's law uses the letter e to represent voltage. When we know the current and resistance, we can calculate the voltage. George performed various experiments on 1k ohm resistor and finally published the treatise in 1827. I is the electrical current flowing through the resistor, measured in amperes. R is the resistance of the resistor, measured in ohms.

The ohms law statement is experimentally derived statement. What current is flowing in the 8 ohm resistor. Ohms law is widely used in electrical engineering for solving circuits.
