What formula calculates total resistance for resistors in series?

Rexttotal=R1+R2+...R_{ ext{total}} = R_1 + R_2 + ...

What happens to total resistance when resistors are added in series?

It increases

Why does resistance increase when resistors are connected in series?

Current must pass through each resistor

What formula finds combined resistance for resistors in parallel?

rac{1}{R_{ ext{total}}} = rac{1}{R_1} + rac{1}{R_2}

How does combined resistance in parallel compare to individual resistors?

Always less than the smallest resistor

What happens to total resistance when more resistors are added in parallel?

It decreases

Why does resistance decrease when resistors are connected in parallel?

Current has multiple paths to take

What is the unit of measurement for resistance?

Ohms (OmegaOmega)

If R1=10,OmegaR_1 = 10,Omega and R2=20,OmegaR_2 = 20,Omega are in series, what is RexttotalR_{ ext{total}}?

30,Omega30,Omega
