Utilizing Faraday's Newmann Lenz law enables the assessment of the induced emf within the loop:

where:

represents the change in magnetic flux

symbolizes the change over time.

#The magnetic flux linked to the coil can be represented as:

Where:

N represents the number of loops.

A denotes the area for each loop ().

B indicates the strength of the magnetic field.

represents the angle between the magnetic field direction and the normal to the loop's area.

=0.0250T/s is indicated as the rate of magnetic field increase.

#Plugging in values into the emf equation:

Thus, the induced emf is

Answer:

(1.6 × 10¹⁸) /s

Explanation:

The current in a wire is calculated using the formula:

I = (Q/t)

where Q represents the total charge of the electrons in the wire

and t denotes time.

Moreover, Q can be expressed as nq

where n is the number of electrons present in the wire

and q is the charge of a single electron, 1.602 × 10⁻¹⁹ C.

This leads us to the equation I = nq/t.

Thus, (n/t) = (I/q) describes the number of electrons flowing per second through a cross-section.

Inserting our current, I = 260 mA or 0.26 A, along with q = 1.6 × 10⁻¹⁹ C, yields:

(n/t) = (0.26/(1.602×10⁻¹⁹)) = (1.62 × 10¹⁸) /s = (1.60 × 10¹⁸) /s

Complete Question:

Picture yourself on an aluminum ladder on the ground, attempting to fix an electrical connection with a metal screwdriver featuring a metallic handle. Since you are sweating profusely, your body has a resistance of 1.60 kΩ.

(a) If you accidentally contact the "hot" wire from the 120 V power line, what current will flow through your body?

(b) What is the amount of electrical power transferred to your body?

Answer:

(a) 0.075A

(b) 9W

Explanation:

According to Ohm's law, the voltage (V) applied to or passing through a body corresponds to the current (I) via the relationship:

V ∝ I

=> V = I x R                 ----------------------(i)

Where;

R denotes the resistance of the body

(a) As mentioned;

Due to wet conditions, the body will conduct electricity, and possesses the following values;

V = supplied voltage = 120V

R = resistance of the wet body = 1.60kΩ = 1.6 x 1000Ω = 1600Ω

Substituting these values into equation(i):

120 = I x 1600

To find I;

I =

I = 0.075A

Thus the current passing through your body is 0.075A

(b) Electrical power (P), which is expressed in Watts (W), delivered to the body is the product of current (I) and voltage (V) received. Thus:

P = I x V           ---------------------(ii)

Where;

I equates to 0.075A   [as derived above]

V is 120V     [as outlined in the question]

Plugging these values into equation (ii):

P = 0.075 x 120

P = 9W

Hence, the electrical power received by your body is 9W
