The voltage delivering 1 watt depends on how many amps are present. We use watts to measure power (P), and amps (I) times volts (E) equals watts.
The urea and water that make up urine are removed from the blood in  the kidney. This is then passed on to the bladder which will be  excreted as urine.
Both are Nitrogen based molecules, but Urea(in urine) is CO(NH2)2, whereas ammonia is NH3. Excess nitrogen in mammals is toxic, and is removed from the body either in the form â¦ of urea or ammonia. Urea is produced in the liver, extracted from the blood by the kidneys, then excreted in the urine. If your kidneys cannot handle the load of nitrogen, then the nitrogen is excreted as ammonia through your sweat.
