What reading level is The Cinematograph book a Complete Practical Guide to the Taking And Projecting book?
To quickly assess the difficulty of the text, read a short excerpt:
M. F. , from one to the other of them. Hence, if two bodies at different potentials are placed in electrical communication with each other, this difference of potential will give rise to an electric current flowing from the one at the higher to the one at the lower potential.
What is the P. D. At the terminals of a dynamo which sends 50 amperes through 20 ohms ? Answer : 50 x 20 = 1, 000 volts = P. D.
What horse-power is needed to run a 65-volt zo-ampere arc lamp ? Answer : i h. P. = 746 watts.... 65 x 10 = 650 watts. /. X = |jg = j^ h. P. , or nearly i h. P THE PROJECTION ARC LAMP 131 The ampere is the unit of flow, or the measurement of current. One ampere of current would result from i volt of pressure of the E. M. F. Passing through a resistance of i ohm.
Generally speaking, to find the amperage, that is, the amount of current in a circuit, the voltage is divided by the resistance, expressed in ohms. . *. A = V -*- O ; or V A = Q. Thus a 20-h. P. Dynamo is running at 500 volts.
What current is it yielding ?
