What else can I help you with?
In a home that has 120 v service heating is provided by electric resistance heat with an overall resistance of 40 ohms hom much heating power will the electric resistance heater generate?
The formula you are looking for is W = E(squared)/R, W = Voltage (squared) divided by Resistance.
What is the resistance of a light globe rated 75 W 240 V when it is operating correctly?
The formula for power is W = v2/R therefore the resistance is v2/W where v2 = v*v or v-squared. due to a font fault these formulas cannot be expressed correctly. But the answer to the question is R = 240*240/75 ohms.
What wattage will be generated if you apply 100 volts to a resistance of 50 ohms?
The formula you are looking for is I = W/E.
Write a program in java to print a statement in reverse order?
/* Input: Do Your Duty * Output: Duty Your Do */ import java.io.*; class RevSent { protected static void main()throws IOException { BufferedReader in=new BufferedReader(new InputStreamReader(System.in)); System.out.print("Enter the Sentence: "); String s=in.readLine(); char ch; short a=0,b=0; for(short i=0;i<s.length();i++) { ch=s.charAt(i); if(ch==' ') a++; } String w[]=new String[a+1]; for(short i=0;i<=a;i++) w[i]=""; for(short i=0;i<s.length();i++) { ch=s.charAt(i); if(ch==' ') b++; else w[b]+=ch; } for(short i=a;i>=0;i--) System.out.print(w[i]+" "); }}
A 14point1 V battery is connected to a 142 resistor Neglecting the internal resistance of the battery calculate the power dissipated in the resistor Answer in units of W?
In a DC circuit, the power dissipated by a resistance is (voltage across it)2 divided by 'R'.P = E2/R = (14.1)2 / 142 = 198.81/142 = 1.4 watts(rounded)

Which has a more resistance a 100 W bulb or a1000 W heater?
A 1000 W heater would have more resistance compared to a 100 W bulb. The higher the power rating of an electrical device, the lower its resistance, as resistance is inversely proportional to power. So, the 1000 W heater would have lower resistance than the 100 W bulb.
What is the real number solution of w2-3w equals 0?
w2-3w = 0 w(w-3) = 0 w = 3 or w = 0
How many watts in 240volts?
There are zero watts in 240 volts. To determine watts, an amperage or a resistance must be supplied. W = Amps x Volts, W = Amps (squared) x Resistance (in Ohms), or W = Voltage (squared)/Resistance.
Is w minus w -w?
No, w-w = 0. Any number minus itself is zero. On the other hand, 0 - w = -w.
What is the work for 49w squared-25w equals 0?
49w2 - 25w = 0 factor out a w w(49w - 25) = 0 set the expression in the parenthesis to that 0 as w already = 0 49w - 25 = 0 49w = 25 w = 25/49 ============so w = 0 -------- w = 25/49 --------------
Three 8.0-W resistors are connected in series What is their equivalent resistance?
The equivalent resistance of resistors connected in series is simply the sum of their individual resistances. Therefore, the equivalent resistance of three 8.0-W resistors connected in series is 24.0 W.

What percent of outer space is empty?
0%. Outer space is filled by Maxwell's Aether with "free space Resistance" z= W/Q =375 Ohms, where W and Q are electromagnetic Charges. Planck's Constant h=QW.
