A security guard walks the equivalent of six city blocks when he makes a circuit around the building. If he walks at a pace of eight city blocks every 30 minutes, how long will it take him to complete a circuit around the building, assuming he doesn't run into any thieves?
Percentage reactance of a transformer (or in general, a circuit) is the percentage of phase voltage drop when full load current flows through it, i.e %X=(IX/V)*100. Now Short Circuit Current is V/X So short Circuit current is I*(100/%X).

An open switch interrupts the flow of electrical current in a circuit, preventing it from completing and thus stopping the operation of connected devices. In contrast, a closed switch allows current to flow freely, completing the circuit and enabling the devices to operate. Essentially, an open switch is like a gap in the circuit, while a closed switch acts as a bridge.
A combinational circuit is a type of digital circuit where the output is solely determined by the current inputs, without any memory elements or feedback loops. This means that the output is a direct function of the inputs at any given time, and it changes immediately when the inputs change. Common examples include adders, multiplexers, and encoders. Combinational circuits are characterized by their use of logic gates (such as AND, OR, and NOT) to perform specific operations on binary data.
The percentage impedance of a transformer is the volt drop on full load due to the winding resistance and leakage reactance expressed as a percentage of the rated voltage.It is also the percentage of the normal terminal voltage required to circulate full-load current under short circuit conditionsThe impedance is measured by means of a short circuit test. With one winding shorted, a voltage at the rated frequency is applied to the other winding sufficient to circulate full load currentZ% = Impedance Voltage x 100Rated Voltage
(6 blocks / circuit) * (30 min. / 8 blocks) = 22.5 min. / circuit

An open circuit or a short-circuit (if that circuit is complete).
no, the circuit won't complete
Current flows through a complete circuit.
An electrical path that is not complete is called an open circuit. In an open circuit, there is a break in the path that prevents the flow of electricity, so the circuit is not complete and devices connected to it will not function.
A parallel circuit
An open circuit
one
Complete circuit.
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.
A closed circuit is a circuit where current can flow because it forms a continuous path, while a complete circuit is a closed circuit that includes all necessary components like a power source, load, and conductive path. So, a closed circuit can be a complete circuit if it has all the necessary components connected together.
