The Current on Resistor R in a Parallel Circuit Calculation

What is the formula to calculate the current on resistor R in a parallel circuit?

The current on resistor R in a parallel circuit can be calculated using which formula?

Answer:

The current on resistor R in a parallel circuit can be calculated using Ohm's law: I = V / R.

When looking at resistors in parallel, the current on resistor R can be determined by applying Ohm's law. In a parallel circuit, the voltage across each resistor is the same. Therefore, we can use the battery voltage V and resistor value R to calculate the current.

Ohm's law states that the current (I) flowing through a resistor is equal to the voltage (V) applied across the resistor divided by the resistance (R) of the resistor. Mathematically, it can be written as I = V / R.

For example, if the battery voltage V is 7.14 V and the resistor R is 4.47 Ω, the current on resistor R can be calculated as follows: I = 7.14 V / 4.47 Ω = 1.60 A.

Therefore, the current on resistor R in this parallel circuit is 1.60 A, rounded to 3 significant figures.
