The total resistance of three resistors connected in parallel will be as compared to the individual value of resistor

A)
B)
C)
D)
Explanation

When resistors are connected in parallel, the total resistance Rtotal is always less than the smallest individual resistance. The formula for calculating the total resistance in parallel is:

Since the reciprocal of the total resistance is the sum of the reciprocals of individual resistances, Rtotalwill always be less than the smallest R.

Correct Answer: A) less


Question: 5 Report Error

कैपेसिटर एसी को ब्लॉक करता है और डीसी को गुजरने देता है।

Capacitor block AC and allows DC to pass through.

A)
B)
C)
D)
Explanation

Explanation:

  • Capacitors do not allow DC to pass through because, in a DC circuit, the capacitor charges up to the supply voltage and then acts as an open circuit, blocking any further current flow.
  • However, capacitors allow AC to pass through because the constantly changing voltage in an AC circuit causes the capacitor to charge and discharge, thus allowing current to flow.

Key Points:

  • Capacitors block DC.
  • Capacitors allow AC to pass by offering a certain reactance depending on the frequency of the AC signal.

Correct Answer: B) false

IPv6 एड्रेसिंग का आकार है

The size IPv6 addressing is

A)
B)
C)
D)
Explanation

The correct answer is (C) 128 bits.

Explanation:

  • IPv6 addressing uses 128 bits to represent an IP address, which allows for a significantly larger address space compared to the 32-bit IPv4 addressing. This larger space is necessary to accommodate the growing number of devices connected to the internet.

Correct Answer: C) 128 bits

Statement required in Arduino program to generate one second delay is

A)
B)
C)
D)
Explanation

The correct answer is (B) delay(1000);

Explanation:

  • The delay() function in Arduino is used to pause the execution of the program for a specified number of milliseconds.
  • To generate a 1-second delay, you need to pass the value 1000 to the delay() function, as there are 1000 milliseconds in 1 second.

Correct Answer: B) delay(1000);
