-- "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.

1 What is the current flowing through a closed circuit if R equals 1000 Ω and V equals 5V?
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%).
How do carbon resistors differ from wirewound resistor?
the power is more evenly distributed in a carbon rod than a wire hi resistance wire wound can have 100s of feet of very fine wire very prone to heat failure solid carbon distributes the heat over the entire volume of the carbon carbon resistors are far better with higher voltages and resistances
Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?
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
Why do the current readings differ for increasing and decreasing values of the incandescent lamp wattages?
While Voltage and Resistance typically remain constant in incandescent lamps: P (Power in Watts) = I (Current in Amperes) times E (Electrostatic energy in Volts [AC and DC]). P=I*E - when P (Watts) goes up so does I (Amps).
How does tensile strength differ from compressive strength?
Flexural strength is resistance offered against bending.Tensile strength is resistance offered against tensile force.

Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.
Why do the reading differ for increasing and decreasing values of the lamp voltages?
at the time of decreasing lamp voltage as the temperature is already high the gas in the lamp is already in ionized state leading to different resistance ,but when increasing voltage the gas is not in ionized state it ready to ionize ,so there is slightly variation in resistance . :)

What aspect of a series circuit is the same for each resistor as well as the total circuit?
Current is the same..... In a series circuit: V=V1+V2+...+Vn and R=R1+R2+...*Rn If voltage remains constant at the source (total circuit), and resistors differ in resistance (R1,R2,...,Rn), and V=I*R, then: I*R=I1*R1+I2*R2+...+In*Rn Seeing as I*R=const and voltage drop across every resistor is proportional to its resistance: I*R=I*(R1+R2+...+Rn) Therefore: I=I1=I2=...=In

What is a resistor used for?
A resistor limits the amount of electrical current that passes through the circuit.Think of kinking a garden hose. The kink "resists" the flow of water.Similarly, a resistor "resists" the current flow and thus lowers the voltage to the following parts of the circuit which that current has to flow through.Another answerSimple...To resist or control the current flow.If a pure conductor (ie, wire) instead of a resistor is used, the path is said to be short circuited and, in theory - but not usually in practice - an infinite current would flow through it if the source was really able to deliver such a current.But, if there is some resistance in its path, the current taken from the source will always be limited to the potential difference produced by the source (measured in volts) divided by the resistance of the path (measured in ohms).I = E/R (Where I is current, E is volts and R is resistance)Another use of a resistor is whenever you need to produce a voltage drop in a circuit. This drop can can then be utilized for some other purpose, noting the voltage will differ depending on the load. If the load varies in resistance, so will the voltage drop.When no resistors are met by the current, the voltage which is actually the amount of work done in moving the charge will tend to zero. This means that the current flows without any resistance and is said to be a dead short to the source.
why are measured current different from calculated values?
Current Differences Explained. Arnel Dela Cruz why are measured current different from calculated values? There are several reasons why There are several reasons why measured current may differ from calculated values:om calculated values: Measurement errors: Measuring instruments are not perfect, and there may be errors in the measurement process. For example, a multimeter may have a small amount of resistance that could affect the measured current. Additionally, there may be errors due to factors such as temperature, electromagnetic interference, or voltage fluctuations. Circuit resistance: The resistance of the circuit can affect the measured current. In some cases, the resistance may be higher than expected, which would result in a lower measured current. Conversely, if the resistance is lower than expected, the measured current would be higher than calculated. Non-ideal components: In real-world circuits, components such as capacitors, inductors, and transistors are not ideal and may have some level of resistance, capacitance, or inductance that could affect the current. Load impedance: If the circuit is connected to a load, such as a motor or a light bulb, the impedance of the load can affect the current. If the load impedance is higher than expected, the measured current would be lower than calculated. Conversely, if the load impedance is lower than expected, the measured current would be higher. Time-varying signals: If the circuit is carrying a time-v
