What is the voltage of a 12 volt battery?

The standard automotive battery in today’s vehicles is a 12-volt battery. Each battery has six cells, each with 2.1 volts at full charge. A car battery is considered fully charged at 12.6 volts or higher. When the battery’s voltage drops, even a small amount, it makes a big difference in its performance.

When a 12v battery is connected across an unknown resistor there is a current of 2.5 mA in the circuit value of resistance is?

In the question the values of voltage V is and the value of the current I through the circuit are given so after substituting these values in the ohm’s law formula we can get the value of unknown resistance. Therefore, we are getting the value of the unknown resistance as 4.8 Kilo ohms.

When a 4V battery is connected across an unknown resistor there is a current of 100 mA?

V=IR V = 4V I = 100 mA = 0.1 A Hence R = V/I = 4/0.1 Ω = 40 Ω.

What does mA stand for on a charger?

The abbreviation mAh stands for milliamps per hour and is the unit that indicates how long (per hour) the power bank can deliver a certain amount of current (mA). A standard adapter with a smartphone has an output of 1000 mA.

What does the symbol mA mean?

The symbol for milliampere is mA. The base unit for a milliampere is ampere and the prefix is milli. The prefix milli is derived from the Latin mille meaning one thousand and is symbolized as m. Milli denotes a factor of one thousandth (1/1000th) which means that there are 1,000 milliamperes in an ampere.

Convert 0.5 Ampere to Milliampere

What is the difference between mA and a?

A milliamp is 1 /1000th of an ampere of electric current. A typical AA battery can provide about 1000 milliamps or so for an hour, but most smaller electronic devices- such as TV remote controls- don’t use anywhere this much current, so the batteries last a long time.

How many volts can a human sustain?

The human body has an inherent high resistance to electric current, which means without sufficient voltage a dangerous amount of current cannot flow through the body and cause injury or death. As a rough rule of thumb, more than fifty volts is sufficient to drive a potentially lethal current through the body.
