The current in a reading lamp would be a small part of the total current in a home. For example, a home may have 100 amp service, while a reading light may draw less than 1 amp, so about 1% of the total.
-- "Amps" and "current" are the same thing. Electric current is measured in units of Amperes. -- The current is always the same at every point in a series circuit, no matter how many resistors of the same or different values are in the circuit.
When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current
The terms a.c. and d.c. stand for alternating current and direct current, respectively.
The voltage drop is equal to the total resistance across which it is dropped multiplied by the current flowing through this resistance. i.e. V=IR (where V is the voltage drop, I is the current and R is the resistance) Thus, I=V/R So I=5/1000 A = 5*10-3 A = 5 mA So the current flowing through your circuit is 5mA. Note that this answer is theoretical, and that it may differ from what you observe in practice due to component tolerances (resistors with the gold band at the end are only accurate to within 10%).
work it out you lazy human
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.

Current assets are different from current liabilities in this sense that current assets are usable in current fiscal year to generate revenue while current liabilities are all those amount or items which are already used in current fiscal year and amount is still payable in current year.
In a DC circuit (battery), the lower potential is always on one 'end' of the circuit so the current always flows in the same direction. In a AC circuit, a wave is generated so each end cycles between high and low potential. Current always flows towards lower potential and changes direction every time the higher/ lower potential changes
putting your but on your head in doing homework
The function is the same in that they both are designed to remove an over current situation by opening the circuit. A tripped breaker can just be reset. A blown fuse needs to be replaced.
A fuse contains a component that melts or breaks in some other fashion when excessive current flows through it. This breaks the electrical circuit. A fuse that has functioned in this way can never be reused. A circuit breaker is a mechanical switch that opens, breaking the flow of electricity when the current goes above a set point. A circuit breaker can be reused by simply closing the switch again once the problem causing excessive current has been taken care of.
The traditional flow theory assumes that current flows from positive to negative, following the direction of conventional current. In contrast, the electron flow theory states that electrons actually move from negative to positive, which is the direction real current flows in a circuit. Both theories describe the movement of charge in a circuit, but they differ in which terminal they consider as the starting point.
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.
A fuse must be replaced if blown, a circuit breaker can be reset.
No. Each circuit has to have its own dedicated circuit. The breaker and wire size differ between the two appliances.
