Physics Drill: Ohmβs Law. Solve the problem using the principles of Ohmβs
Law below. Show your complete solution.
1. Find the current through a resistor of resistance π = 2Ξ© if the voltage across
the resistor is 6V.
2. While repairing an electric bulb socket, an electrician gets a mild shock when a
current of 0.0050 A passes through him. The same electrician was killed by a
current of 0.15 A when he turned on an electric bulb while taking a bath. The
voltage in each situation is equal to 120 V. Find the resistance of the electrician
in each situation.
3. A typical value of the resistance of a person from hand to hand through the
body is 2,000 Ξ©. If a person with this resistance accidentally touches a 220 V
live wire, what current passes through the person?

done in moving 5C of charge across the cell.
3. A group of electrons of net magnitude of charge, π = 0.50 πΆ, passes through a
cell of voltage, πππππ = 20π, from the (+) to the (-) terminal. What is the change
in energy, βπΈ, of the group of electrons as they move across the terminals?

Thomas Private Limited Company is about to start production of new products to
sell to customers. Before the start of the new production, it costs the company $
200,000 to construct the factoryβs building. Once the construction is over, the cost
per unit of production is estimated to be birr 20. Upon selling, the company will
incur a 20% commission expense. Moreover, the price per unit of products is
decided to be Birr 50.
Required:
a)
Construct the total cost equation in terms of quantity.
b)
Determine the break-even quantity (Revenue)
