If a series street light circuit has a total voltage of 2400 volts and each bulb has a voltage drop of 48 volts, how many street lights are in the circuit?

To determine how many street lights are in a series circuit with a total voltage of 2400 volts and each bulb having a voltage drop of 48 volts, you would divide the total voltage by the voltage drop per bulb.

In this scenario, the total voltage supplied to the circuit is 2400 volts, and each street light bulb uses 48 volts. The calculation would be:

Total voltage / Voltage drop per bulb = Number of bulbs (or street lights)

So, you would perform the calculation:

2400 volts ÷ 48 volts per bulb = 50 bulbs.

This shows that there are 50 street lights in the series circuit.

Understanding this concept is key in electrical theory, especially in circuits, where total voltage is divided among the components in series. Each additional light decreases the voltage available for the other bulbs equally, reinforcing the importance of knowing how voltage is distributed in such circuits.
