vadevalor said:If current flows through a voltmeter in parallel first then it flows back to an ammeter -- any effect on the ammeter and voltmeter reading? (Do they increase or decrease?)
I would assume current measured by the ammeter is the same as when no current flows through the voltmeter, because although current splits before the voltmeter, the current is added up when it leaves the point of split and heads for the ammeter. But i suspect this is not true.
Also, I only rely on using V=IR, but it doesn't work sometimes, so are there other equations to use if this doesn't work?(as in it doesn't prove the increase or decrease)
Electricity is the flow of electric charge, usually carried by electrons, through a conductive material. It is a form of energy that is essential for most modern technology and daily life.
Current is the movement of electric charge in a circuit. It is caused by the flow of electrons from a negative to a positive electrical potential. The amount of current is measured in amperes (A) and is dependent on the voltage and resistance in the circuit.
AC (alternating current) is when the flow of electric charge periodically reverses direction, while DC (direct current) is when the flow of electric charge remains in the same direction. AC is typically used for large-scale power distribution, while DC is used for smaller electronic devices.
Electricity can be generated in multiple ways, such as through the use of generators, batteries, solar panels, or wind turbines. These methods involve converting other forms of energy, such as mechanical or chemical energy, into electrical energy.
When working with electricity, it is important to follow safety precautions to avoid the risk of electrical shock or injury. These include wearing protective gear, ensuring proper grounding and insulation, and turning off power sources before working on electrical equipment. It is also important to have a basic understanding of electrical circuits and to never touch live wires or outlets.
