وہیٹ اسٹون پل میں ایک ___ میٹر کو نل ڈیٹیکٹر کے طور پر استعمال کیا جاتا ہے۔
- Voltmeter
- Galvanometer
- Ammeter
- Ohmmeter
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A galvanometer is used as a null detector in a Wheatstone bridge.
It detects the zero current condition, indicating that the bridge is balanced.
کو انڈکٹنس کی پیمائش کے لیے استعمال کیا جاتا ہے۔ _____
- Hay Bridge
- Wheatstone Bridge
- Kelvin Bridge
- RLC Meter
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Hay Bridge is used for the measurement of inductance.
It is specifically designed to measure the inductance of coils with high accuracy.
ایک انڈکٹر توانائی ذخیرہ کرسکتا ہے۔ یہ توانائی ______ میں محفوظ ہے؟
- Magnetic Field
- Electric Field
- Thermal Field
- Capacitive Field
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
An inductor stores energy in its magnetic field.
When current flows through the inductor, it generates a magnetic field around it, which stores energy.
آر گیٹ کا آؤٹ پٹ زیادہ ہوگا جب ______؟
- Any of the inputs is high
- All inputs are low
- None of the inputs is high
- All inputs are high
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The output of an OR gate will be high when any of the inputs is high.
An OR gate outputs a high signal if at least one input is high.
یو جے ٹی میں ________ مزاحمت ہے۔
- Positive
- Zero
- Negative
- Infinite
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
UJT (Uni-Junction Transistor) has negative resistance.
This characteristic allows it to be used in oscillators and timing circuits.
درجہ حرارت میں اضافے کے ساتھ کس جز میں مزاحمت کم ہوتی ہے؟
- PTC Thermistor
- Resistor
- NTC Thermistor
- Variable Resistor
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Component: Thermistor (specifically an NTC thermistor)
- Why: As temperature rises, more charge carriers become available in the semiconductor material
- Result: Resistance decreases with rising temperature
- Contrast: Most metals do the opposite — resistance increases with temperature (PTC behavior)

- Active Network
- Complex Network
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A network containing one or more sources of EMF is known as an Active Network.
Active networks include elements like batteries or generators that provide energy to the circuit.

سپرپوزیشن تھیوریم ______ پر لاگو ہوتا ہے؟
- Nonlinear Circuits
- Linear Response Only
- Digital Circuits
- Time-Varying Signals
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Superposition Theorem is applicable to linear response only.
It states that in a linear circuit with multiple sources.
The response (voltage or current) can be calculated by summing the responses due to each source independently.
