If a 72-candela light source is located at a distance of 3 meters from a surface, the illuminance on the surface is 8 lux.
E = I / s²
E = 72/9 = 8 lux

A circuit contains two devices that are connected in parallel. If the resistance of one of these devices is 12 ohms and the resistance of the other device is 4 ohms, the total resistance of the two devices is 3 ohms.

Solution:
Total resistance = 12*4 / (12+4) = 48/16 = 3 ohms.

A series circuit contains a generator, two devices, and connecting wires. The resistances of the two devices are 15 ohms and 10 ohms. The voltage supplied by the generator is 75 V. 30 V will be the voltage drop in the device with 10 ohms of resistance. Solution: 75/(15 + 10) = 3V. per ohm. (3V x 10R) = 30V.
