Circuit City made a comeback in 2018. Under its new owner, Ronny Shmoel, Circuit City planned to open kiosks, stores within other stores and eventually its own showrooms. The brand is still alive but it’s far from being a behemoth it was twelve years ago. How many stores did CircuitRead More →
: the ratio of the effective current to the effective electromotive force in an alternating-current circuit multiplied by the sine of the phase difference between current and electromotive force. What is the formula of susceptance? What is Susceptance? As conductance is the complement of resistance, there is also a complementaryRead More →
Will the bulb glow in the circuit shown in Fig. 12.6? Explain. No the bulb will not glow in this circuit because the switch is open and the circuit is incomplete. Do bulbs glow in circuits? No, the bulb would not glow in the given circuit because one of theRead More →
2. Why clamp diodes are used in comparator? Explanation: The diodes protect the op-amp from damage due to excessive input voltage. Because of these diodes the difference input voltage of the op-amp is clamped to 0.7v or -0.7 v, hence these diodes are clamp diodes. What is clamping circuit Theorem?Read More →
Wi-Fi uses (a kind of) FDM to allow multiple channels. These channels can be used independently or they may be bonded to increase the bandwidth of a single link. On copper, FDM and TDM aren’t commonly used in LANs (due to baseband signaling) but xDSL and DOCSIS use FDM (they’reRead More →
In welding, Open Circuit Voltage or OCV (simply no-load voltage) is the voltage (In volts) between the electrode and the work piece(or the earth) when welding is not in progress. So, OCV is the voltage exists between negative and positive pole of a welding machine in ON mode but withoutRead More →
The open-circuit voltage is a forward bias voltage on a solar cell. In the I-V characteristics of a solar cell, the open-circuit voltage is as shown below figure. From the above equation, Voc and temperature are directly proportional. Hence, Voc increase linearly with respect to temperature. What is the valueRead More →
The term open circuit means that no current flows through the cell. Here, the continuity of the circuit is broken as a result of which the current does not flow. … Open circuit is any circuit that not pass current when potential difference is established across it, hence its resistanceRead More →
