Power output of the broiler will decrease drastically.
Broiler has very large resistance and its working principle is dependent on the heat generated by passing current through it.
Short circuit provides an easier path for the current and hence most of the current passes through it. Hence, power output will be very less.

If we say that something acts as a "short circuit," it means that the path has very low resistance to current flow. Which of the following represents a situation that could be described as a "short circuit?" a capacitor in a circuit with a very low frequency AC generator a resistor in a circuit with a very low frequency AC generator a capacitor in a circuit with a high frequency AC generator a resistor in a circuit with a high...

4. In the circuit shown below, a parallel RC network creates a frequency-dependent feedback path for the inverting amplifier block with gain Av (a large negative value). Use the Miller theorem to find the equivalent input impedance Zin as indicated in the diagram and then show that Vin/Vsig is given by the symbolic expression shown below right. Choose a value for capacitor C to make the upper cut-off frequency fH equal to 22 kHz. Repeat the calculation for the case...

2. (Short Circuits) An Ammeter is a device that can measure current through a circuit compo- nent. It is devised to be a device that has a VERY LOW internal resistance r. You use the device by connecting the device in series with the branch of the circuit you want to measure the current through. Suppose you accidentally connected the ammeter in parallel with a bat- tery and another resistor (with resistance R»r). Using Kirchoff's rules, show that when s...

In circuit 1, four resistors are connected purely in parallel to a battery. Three resistors are unknown and one of the resistors is 6 Ohms. In circuit 2, the resistor whose resistance is known (6 Ohms is removed from the circuit and the other three resistors are connected purely in parallel to the same battery. The power output of the battery in circuit 1 is 5.1 Watts more than the power output of the battery in circuit 2. What is...
