To determine the wattage of each heater strip, you first need to understand the total power consumed by the circuit and how it divides among the heater strips connected in parallel.

In a parallel circuit, the total current flowing through the circuit is equal to the sum of the currents flowing through each individual branch (or heater strip, in this case). Given that the total current for the system is 8.33 amperes and there are 10 heater strips, you can find the current flowing through each strip.

First, calculate the current per heater strip:

[

\text{Current per heater strip} = \frac{\text{Total current}}{\text{Number of heater strips}} = \frac{8.33 \text{ A}}{10} = 0.833 \text{ A}

]

Next, to find the power (wattage) consumed by each heater strip, you can use the formula for electric power:

[

P = V \times I

]

where (P) is the power in watts, (V) is the voltage, and (I) is the current in amperes. Here, the voltage for each heater strip is given as 120 volts, and the
