Sagot :
The resistance of the furnace is 2.4 ohm
Given,
P=24kW, V=240v,
P=[tex]\frac{V^{2} }{R}[/tex], 24kW=[tex]\frac{240^{2} }{R}[/tex], Therefore R=2.4 ohm
Resistance
A force that opposes the flow of current is electrical resistance, often known as resistance to electricity. It acts as a gauge for how challenging it is for current to flow in this fashion. Ohms (), which represent resistance values, are used. Electricity will move from high to low when an electron difference exists between two terminals. This flow is opposed by resistance. Lower currents occur at higher resistance levels. The opposite is also true: the current increases as the resistance decreases. The Greek letter omega (), which represents resistance, represents ohms. German physicist Georg Simon Ohm (1784–1854), who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance known as an ohm. Ohm's Law was developed under his direction.
