Apply the junction rule to the junction labeled with the number 1 (at the bottom of the resistor of resistance R2).
Answer in terms of given quantities, together with the meter readings I1 and I2 and the current I3.
ΣI=0 =
Part C
Apply the loop rule to loop 2 (the smaller loop on the right). Sum the voltage changes across each circuit element around this loop going in the direction of the arrow. Remember that the current meter is ideal.
Express the voltage drops in terms of Vb, I2, I3, the given resistances, and any other given quantities.
Σ(ΔV)=0 =
Part D
Now apply the loop rule to loop 1 (the larger loop spanning the entire circuit). Sum the voltage changes across each circuit element around this loop going in the direction of the arrow.
Express the voltage drops in terms of Vb, I1, I3, the given resistances, and any other given quantities.
Σ(ΔV)=0 =
