P = IV
I = V / R
I = 14 / (9 * 4) = 14 / 36
IV = (14 / 36) * 14
IV = 5.444 Joules

lf all resistors are in parallel, yes. If they are in series, not necessarily - this depends on the resistor values (if they are all the same, then yes, if not no).
resistor isdefined as the opposing the current flow in a circuit. capacitor is defined as the store the electric field in one forth of the cycle and the another quarter cycle stored energy will be released
28 + 56 = 84 ohms
A resistor may be used in series charging for current limiting, filtering, or as a signal isolater. Resistors across caps are to discharge them for your safety or equalize voltages across the caps in series filtering circuit.
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.

A series circuit
The resistance of a series circuit is simply the sum of the individual resistors.
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
If the circuit consists of resistors only, you simply add the values of all the resistors, in ohms.
current in series depends on values of resistors. more resistance less current will flow through and viceversa
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
Series circuit.
It means the two resistors have same resistance
