What is the difference between an atom and an ion?

Detailed Solution for Test: Electrical Circuits- 1 - Question 2

An ion is a particle or collection of particles with a net positive or negative charge.

An atom is the basic unit of an element. The identity of an element is determined by the number of positively charged protons in the atom’s nucleus. A stable atom contains the same number of electrons as protons and no net charge.

In a four-branch parallel circuit, there are 10 mA of current in each branch. If one of the branches is open, the current in each of the other three branches is:
Detailed Solution for Test: Electrical Circuits- 1 - Question 7

All the four branches are connected in parallel, so the voltage across every branch is same. If one of the branch is open, it doesn’t affect the other branches current. Because the voltage and impedance across remaining branches will remain same.

The number of mesh currents required in the circuit given below is:
Detailed Solution for Test: Electrical Circuits- 1 - Question 8

In the given network

Number of branches (b) = 9

Number of nodes (n) = 5

Number of mesh currents = b – n + 1

= 9 – 5 + 1 = 5

A current source and a voltage source are connected in parallel as shown below. Suppose that vs = 12 V and is = 3 A.What is the power supplied by each source?
Detailed Solution for Test: Electrical Circuits- 1 - Question 10

Power supplied by current source = 12 × 3 = 36 W

Here current source acts as source

Power supplied by voltage source = 12 × (-3) = -36W

Here voltage source acts as sink.

A voltage source of 10 V and resistor are connected in series. Specify the resistance R so that both of the following conditions are satisfied:

i > 40 mA and the power absorbed by the resistors is < 0.5 W.
Detailed Solution for Test: Electrical Circuits- 1 - Question 11

Given that,

I > 40 mA


⇒ R > 200

⇒ 200 < R < 250

An equivalent single current source between ‘A’ and ‘B’ in the following figure will be:
Detailed Solution for Test: Electrical Circuits- 1 - Question 13

An equivalent single current source is nothing but Norton’s equivalent

To find short circuit current (IN)

Apply kVL

-5 – 10 + 10 I + 5 = 0

⇒ I = 1A

Apply kCL at point B,

IN = 1 + 1 = 2A

To find Norton’s resistance, we need to short circuit the voltage sources and open circuit the current sources.

RAB = (10 || 10) = 5Ω

In the interconnection of ideal sources shown in the following figure, it is known that the 60 V source is absorbing power. Which of the following can be the value of the current source i?
Detailed Solution for Test: Electrical Circuits- 1 - Question 14

kCL at O

⇒ I1 + I = 12

⇒ I = 12 – I1

By the above equation,

I should be less than 12 A.

Hence 10 A can be the value of the current source I.
