27. Resistors & DC Circuits

Kirchhoff's Loop Rule

Kirchhoff's Rules (Laws) - Introduction

i6Ω = 4.67 A, V1 = 1.8 V

i6Ω = 4.67 A, V1 = 24 V

i6Ω = 0.67 A, V1 = 26 V

i6Ω = 0.67 A, V1 = 30 V

For the circuit below, calculate&nbsp;(a) the voltage V1 shown, and&nbsp;(b) the current through the 6-Ohm resistor.<img src="https://static.studychannel-prd.pearsonprd.tech/courses/physics/thumbnails/images/2efe2e18"alt=""/>
