Will there be a current flow if the resistor burn out which is connected in series?
Leopang26
Depends what you mean when you say "burn out". That's actually a pretty imprecise term.
Usually, when we talk about a single passive component "burning out", we mean that some part
of it became so hot that the conducting path melted at some point and became "open" at that point.
When that happens, the open gap has a very high resistance, and current can't flow across it.
So I guess we'd have to say 'no'; when current can't flow through the resistor, then there is
no current flow through the resistor.

When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
At what level will typical resistors burn out?
A typical resistor will burn out when it dissipates power in excess of double its power dissipation rating for an extended period of time. The power dissipated by a resistor is equal to I2R or E2/R, where E = the voltage across the resistor I = the current through the resistor R = the resistance of the resistor
Why does resistor burn up?
cause its bad,replace with higher wattage rating.too much current !!
Can a house be connected in series circuit?
The breaker panel. Breakers are placed in series with all outlets.
Why wouldn't the shunt resistor in the ammeter protect the ammeter when the ammeter is connected in parallel?
Connecting an ammeter in parallel subjects that ammeter to the full supply voltage. The shunt resistor is not designed to sustain that value of voltage and will burn out. Also, the clue is in the word 'shunt' (which means 'in parallel') which means that the coil will also burn out!
Why must an LED always have a resistor connected in series with it?
An LED usually has a resistor connected in series with it because an LED (light emitting diode) is not linear in current to voltage (like a resistor) and has to be operated within specified current and voltage conditions. In most circuits the supply voltage is higher than the forward voltage of the LED so the LED would burn up from too much current without a current limiting resistor in series. The resistor sets the voltage and current to a good operating point (voltage and current) for the LED by dropping some voltage across it. The operating point varies depending on the size, type and manufacturer of an LED so the LED's data is used to select the right resistor size for a given voltage source.

How do you measure current without an amp meter?
Depends on the current. Put a resistor in-line with the current, then measure the voltage across the resistor. V=RI. So, divide the measured voltage by resistor value. Be careful with the size of the resistor, as Power dissipated in a resistor is R*I^2 or V^2/2. So, a 1-Amp current into a 1 Ohm resistor will result in a 1Watt power dissipated in the resistor. If it's too small, it'll burn. Also, notice that if you do that, you haven't measured the current in the original circuit. You've measured the current when an extra resistor is installed in the original circuit, and that's different.
Does the number of batteries change the brightness of the bulb?
It will if the batteries are connected in series. If they are connected in parallel, the lamp will burn longer, but not brighter.
What will happen if 110 vac motor connected with 230 vac?
It will burn due excess current .

Why do resistors burn out?
Most often a resistor fails because it is unable to properly dissipate the heat generated by the current flow. A resistor rated for more power (higher wattage) may resolve the problem.

If voltage constant when the current increases what does the resistance do?
In an electric circuit, ratio of current and voltage is constant which is known as the resistance of the circuit. If voltage or current is to be changed the resistance has to be changed. You cannot keep an invariable resistance in the circuit and increase current while keeping voltage as constant.Hence to vary the voltage or current in a circuit different equipments like rheostat,potentiometer are used.
Did the light bulb light up when the dry cells were connected in parallel?
If dry cells are connected in parallel, they will supply more current to the bulb, which will cause it to glow for a longer period of time, but at the same brightness as if only a single cell were used. When the cells are connected in series, the voltage is increased, which will cause the bulb to burn more brightly. If the voltage is increased past the safe point for the bulb, its life will be shortened and it may burn out rapidly. In series, the voltages add. In parallel, you essentially have a larger cell of the same type (cell as in battery of one).
