Maximum 1 A current can pass through a bulb haVing resistance 100 Omega . What will be the power of this bulb?

When current passes through resistor due to its resistive property heat is produced. Error in measurement of resistance, current and time is 1%, 2% and 1% respectively, then what will be percentage error in measurement of heat energy ?

Eels are able to generate current with biological cells called electroplaques. The electroplaques in an eel are arranged in 100 rows, each row stretching horizontally along the body of the fish containing 5000 electroplaques. The arrangment is suggestively shown below. Each electroplaques has an emf of 0.15 V and internal resistance of 0.25 Omega The water surrounding theeel completes a cricuit be ween the head and its tail. If the water surrounding it has a resistance of 500 Omega , the current an eel can produce in water is about
