Power Formula
1. W = V x A
W = 120 x 6
W =720 watts

2. V = W / A
V = 150 / 1.5
V =
100 volts

3. A = W / V
A = 150 / 120
A = 1.25 amps

4. A = W / V
A = 1,000 + 1,000 / 120
A =
16.67 amps

MF Story Problems
1. S = MF x D
.25 x 20 = 5'-0" pool of light

2. MF = S / D
4'-0" /10'-0" = MF factor of .4

3. D = S / MF
35'-0" / .7 = Hang instrument 50'-0" away from proscenium
