Question

state ohms law and describe an activity to verify ohms law.

Answer 1

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship in three ways:

I = V/R

R = V/I or

V = IR

where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.

Example-
If the apply Voltage across a Circuit is 50V, and a series connected Resistor in the circuit which resistance is 10 Ω, then what would be the Current in that Circuit?

Answer 2

where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
