R 10 Ohm

R 10 Ohm. Let the net resistance between points A and B be R AB Then 1 / R AB = 10 ohm ∴ The total resistance of the circuit = 8 ohm + 10 ohm = 18 ohm (b) Current I = Voltage / Total resistance I = 18 / 18 A I = 01 A Hence the reading of ammeter is 01 A Question 31 A cell of emf 2 V and internal resistance 12 Ω is connected to an ammeter of resistance 08 Ω and two resistors of.

Ohm’s Law Equation V = IR where V is the voltage across the conductor I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current Relationship Between Voltage Current and Resistance Analyzing row 12 and 3 we come to understand that doubling and tripling the voltage leads to doubling and a tripling of.

Experiment 15: Ohm’s Law

This means that of your 12 volts from the battery 2 volts will be used up by the LED itself so your Ohms law calculation should be based on 10 volts instead The true formula should actually be (12Vf)/0015=66666 Ohms (recurring for the maths wizards amongst you!) The closest value to this in E12 range is 680 Ohms so ideally this should be the value to use As a matter of safety.
