RT = R1 + R2 + R3 + R4 + ...

The RT formula is usually written this way.

The three dots, ...,

simply mean that you use as many R's as you are given.

If you are given two

R's, then you would add together _________ R's.

46.

Solve these formulas.

Use your metric number table.

RT = R1 + R2 + R3 + R4 + ...; R1 = 5K, R2 = .4M

1.

RT = ________________

2.

E = IR; I = 3m, R = 3K

E = _________________

70.

The first step to solving this problem would be to find a ____________

denominator.
