question 20 of 30. which of the following equations can be used to calculate the current in a circuit? a. i = v/r b. i = r/v c. i = v/i d. i = ir
Answer
Brief Explanations:
The current in a circuit is calculated using Ohm's Law, which states current (I) equals voltage (V) divided by resistance (R), i.e., ( I = \frac{V}{R} ).
Answer:
A. ( I = \frac{V}{R} )
