- Three in parallel
- Three in series
- Two in parallel
- Two in parallel and one in series
Correct answer: 4. Two in parallel and one in series
Solution: Req = (1000 || 1000) + 1000 = 500 + 1000 = 1500 ohms
Voltage dependent resistors are generally made from
Voltage dependent resistors are generally made from
- Charcoal
- Graphite
- Nichrome
- Silicon carbide
Correct answer: 3. Nichrome
The closed switch has a resistance of
The closed switch has a resistance of
- About 50 ohms
- About 500 ohms
- Infinity
- Zero
Correct answer: 4. Zero
When electric current passes through a bucket full of water, lot of bubbling is observed. This suggests that the type of supply is
When electric current passes through a bucket full of water, lot of bubbling is observed. This suggests that the type of supply is
- AC
- DC
- Any of above
- None of these
Correct answer: 2. DC
An open resistor, when checked with an ohmmeter reads
An open resistor, when checked with an ohmmeter reads
- High but within tolerance
- Infinite
- Low but not zero
- 0
Correct answer: 2. Infinite
