I Want Ti Srify Engineering

Question 1

Infinite resistance circuit?

Answer 1

Look at the end of the circuit and work backwards,
Work out what each loop will always be equal too
Simplify

Question 2

For elec questions might be useful to

Answer 2

Analyses without resistor first

And remember Kirchhoff second law all the voltsge in a loop must be used, if this isn’t with a component shared with another loop, can safely say that that loops get all voltage!

Question 3

For 3d circuits what to do

Answer 3

Find common point with same voltage and put a wire through such that the current wouldn’t change etc, now rearrange inside and work it out

Question 4

Remember a wire going through points of same voltage is

Answer 4

List noting, no current nothing

Question 5

To find voltsge at a point m just

Answer 5

Kill the circuit and use voltage drops (assuming wires not residotbem voltage from one component to the next I. A wire is constant

Question 6

Okay if Earth at any point for circuit

Answer 6

Means that it’s 0 there
