Test: Basic & Electric Circuits- 1 - Question 1

### If the power supplied by the 20 V voltage source shown in figure below is 60 W then, the power supplied by the unknown circuit element (x) will be Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 1

we know that   Test: Basic & Electric Circuits- 1 - Question 2

### In the network of figure shown below, I1 = 0.05 A, I2 = 0.1 A , R = 50 Ω. The unknown current source has strength of i, If 100 J of energy is delivered to I2 in 1 min, the magnitude of i will be Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 2

energy dissipated in where p=vi Since power is constant, therefore Applying KCL at node v, we have Test: Basic & Electric Circuits- 1 - Question 3

### The energy required to move 120 C charge through 3 V is

Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 3

W=QV=120 X 3 = 360J

Test: Basic & Electric Circuits- 1 - Question 4

For a given voltage, four heating coils will produce maximum heat, when connected

Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 4

Maximum heat produced is for P to be maximum, Req should be minimum which is minimum of all four coils are connected in parallel.

Test: Basic & Electric Circuits- 1 - Question 5

Given figure shows a plot of d.c. voltage applied to a resistor of 5 Ω for 15 seconds. The total energy consumed by the resistor is Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 5

energy = power x time  Hence, the heat consumed by the resistor

= 1140 J

Test: Basic & Electric Circuits- 1 - Question 6

The charge in a capacitor is given by if the voltage across this capacitor be v(t) = sin t, the current i(t) through the capacitor is

Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 6

The current through.the capacitor is Test: Basic & Electric Circuits- 1 - Question 7

The unit of reactive power is

Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 7

Active power does do work, so it is the real axis. The unit for power is the watt (symbol: W). Apparent power is often expressed in volt-amperes (VA) since it is the product of rms voltage and rms current. The unit for reactive power is var, which stands for volt-ampere reactive.

Test: Basic & Electric Circuits- 1 - Question 8

The unit of electrical energy is

Test: Basic & Electric Circuits- 1 - Question 9

The given signal is Detailed Solution for Test: Basic & Electric Circuits- 1 - Question 9

Given signal is a ramp signal f(t) = A(t), which is neither an energy signal nor a power signal.

Test: Basic & Electric Circuits- 1 - Question 10
