I’m looking for some good ohms law based calculations work sheets. With the answers. I’m looking for both series and parallel questions. Im looking for calculation questions rather than principles, which a lot of work sheets are based on from what I’ve found.

What do you mean by series and parallel questions? If resistors are in series, they have the same current. If they're in parallel, they have the same voltage across them.

Think circuits.

Currents flow in circuits through conductors. In other words, a conductor conducts current.
On the other hand, resistance resists the flow of current.
Resistance is the inverse of conductance.

If we give mathematical symbols to resistance as R and conductance as G,
then

R = 1/G
or inversely
G = 1/R

When resistors are connected in series, the resistance add. In other words, the total resistance is the sum of each individual resistance.

When resistors are connected in parallel, the conductance add. In other words, the total conductance is the sum of each individual conductance. Since current has more paths to flow, conductance increases.

Sorry, meant worksheets with questions on where I can practice using the formulas for both series and parallel circuits

Is it hard for you to implement in Excel the proposed solutions? They take little effort and just basic knowledge of Excel.

Have you tried this?

Hi Tt,
What will the voltage at Va be?
