It is desired to build an electric heater with a power of 1000 W
that works with a potential difference of 120 V connected to its
ends. If the heater consists of a 2 meter long nichrome wire.
calculate
- The current that must flow through the device so that it works at
the desired power - The total resistance of the device
- The dimensions of the nichrome wire
- A second wire (of unknown values) is connected in series to the
nichrome wire. If a voltage of 120 V is applied to the entire
circuit, a potential difference of 40 V is measured across the ends
of the unknown wire. What is the resistance of this new wire?
