Question
Download Solution PDFFind the current through the 8 Ω resistor.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 1):
Concept:
When two resistors R1 and R2 are connected in series, Then the total resistance will be
RT = R1 + R2
When two resistors R1 and R2 are connected in parallel, Then the total resistance will be
RT = (
The voltage across the resistor given by ohms law
V = I R
Current divider rule:
The current through R2 is given as
Calculation:
Given
The total resistance is given by
RT = (
=
=
The total current
I =
I =
=
By the current divider rule
The current through 8 Ω resistor is
=
=
