If an electric circuit has 30ohms and 10amps. How many volts the battery voltmeter should read?

Answers

Answer 1

Answer:

Voltage = 300 Volts

Explanation:

Given the following data;

Resistance = 30 Ohms

Current = 10 Amps

To find voltage;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage. I represents current measured in amperes. R represents resistance measured in ohms.

Substituting into the equation, we have;

[tex] V = 10 * 30 [/tex]

Voltage = 300 Volts.

Therefore, the battery voltmeter should read 300 Volts.

A) Semi automatic, Automatic
B) Fixed automatic, Flexible Automation
C) Automatic, Semi Automatic
D) Flexible Automatic, Fixed Automatic

Answers

Answer:

D.

Explanation:

In automated welding, defined as “welding with equipment that requires only occasional or no observation of the weld, and no manual adjustment of the equipment controls,” the welder's involvement is limited to activating the machine to initiate the welding cycle and observing the weld on an intermittent basis.

What is arc welding?

Arc welding is a type of welding that uses an electric arc to generate heat in order to melt and join metals.

Using either direct (DC) or alternating (AC) currents, a power supply generates an electric arc between a consumable or non-consumable electrode and the base material.

Arc welding is widely used to join materials and is used in a variety of industries. Arc welding is used in the aerospace industry to manufacture and repair aircraft, join sheeting, and for precision work.

Arc welding is used in the automotive industry to join exhaust systems and hydraulic lines.

During shielded metal arc welding, the work clamp completes the electrical circuit.

Thus, it is to complete electric circuit.
