Which symbol and unit of measurement are used for voltage?

symbol: V; unit: A
symbol: R; unit :
symbol: V; unit: V
symbol: R; unit: V

Answers

Answer 1

Answer:

I should be V or E I am not sure what you mean by unit.

Answer 2

The symbol and standard unit of measurement ( S.I ) are used for voltage are V and V respectively.

Option C) symbol: V; unit: V is the correct aswer.

What is voltage?

From ohm's law, the potential difference or voltage between two points is directly proportional to the current flowing through the resistance.

Hence, V = IR

Voltage is the measure of specific potential energy per unit charge between two points.

The SI unit of voltage is volt represented as V

Hence, the symbol and standard unit of measurement ( S.I ) are used for voltage are V and V respectively.

Option C) symbol: V; unit: V is the correct aswer.

A car starts from rest and moves along the positive x-axis with a constant acceleration of 5 m/s/s for 8 seconds. It then continues with constant velocity, i.e. the velocity it attains at 8 seconds for the next 5 seconds. What will be the distance covered by the car in the first 12 seconds of its motion?

Answers

Answer:

340

Explanation:

Because you are moving at 5 m/s^2 for 8 seconds, you need to do some arithmetic to get the distance covered in the beginning. TO do this, you do 5 + 5*2 + 5*3 + 5*4 + 5*5 + 5*6 + 5*7 + 5*8, and once you have passed eight seconds, you need 4 more seconds with constant velocity, or 4(5*8). Your final equation would be 5+10+15+20+25+30+35+40+40+40+40+40. Hope this helps!

To increase the current in a circuit, which can be increased?


voltage

resistance

interference

ohms

Answers

Option A. voltage

How can you increase the current in a circuit?

In a circuit, cutting the resistance by half and leaving the voltage unchanged will double the amperage across the circuit. If the circuit's resistance remains unchanged, the amperage in a circuit can be increased by increasing the voltage

What increases as the current increases?

Ohm's law states that current is directly proportional to voltage but inversely proportional to resistance. At constant resistance, current increases as voltage increases and vice versa. At constant voltage, current decreases as resistance increases and vice versa.

A circuit has a current of 2.4 A. The voltage is increased to 4 times its original value, while the resistance stays the same.

How should the resistance change to return the current to its original value if the voltage remains at its increased amount?

It should decrease to one-half of its value.
It should decrease to one-fourth of its value.
It should increase to two times its value.
It should increase to four times its value.

Answers

Answer:

It should increase to four times it's value.

Explanation:

This is because current goes up with voltage (which is a positive correlation). And for the current to not be over used or over work the load you work slow it down by multiplying the resistance to what it would be if it had a reaction to the voltage increasing.

Answer:

D.) It should increase to four times its value.
